UNITED STA I AUTOMOBILE-211MB Application filed December 30, 1915.

To all whom it may come-m:

Be it known that I, FREDRICK P. Scrnrnrr, a citizen of the United States, residing at Cook, in the county of Johnson, Stateof Nebraska, have invented a new and useful Automobile-Pump; and I do hereby declare the following to be a full, clear, and exact description of the invention, such will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to a tire pump attachment for automobiles, and has for its object to provide a device of this character which embodies novel features of construction whereby the rotation of one of the drive wheels can be utilized to actuate the pump when the wheel is jacked up above the ground.

Further objects of the invention are to provide a device of this character which is comparatively simple and inexpensive in its construction, which can be readily applied to any automobile, which can be quickly thrown into operative position, and which will enable the power of the engine to be utilized for driving the pump, thereby avoiding the tedious and back breaking op eration of pumping tires by hand.

With these and other objects in view, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims.

For a full understanding of the invention reference is to be had to the following description and accompanying drawings, in which Figure l is a fragmentary side elevation of an automobile showing a pump attachment constructed in accordance with the invention applied thereto, portions being broken away and shown in section.

Fig. 2 is a bottom plan view of the pump attachment.

Fig. 3 is a transverse vertical sectional view through the pump casing and guide.

Fig. 4; is a view similar to Fig. 1 showing a modification.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawings, the reference Specification of Letters Eatent.

character A designates tion of annutoinobile Vllli. conventional. construction. 5 wheel-1, running boa rd 2. llfl ountcd in a convenivehicle frame and wheel 1 is a slide 4;. said to le moved toward and away it an 1 of the wheel 1. fu' :able 9' are shown as engagin the edg 4i: to direct it in its lackward and or move rents, and the slid carries the c der (3 of an air pump. The piston roe the air pump ged by a S and arr-an" to reciprc: forth, the ion 'ard end of th p ston ing pivotall connected by a i wheel l0 which is iournaled 1 ll projecting from the slide l. p I cry of the wheel 10 is grooved for ment with the tire l of the w that when the slide is moved to in" 1 wheel into a tirm engagement with the pump will be actuated by the of the drive wheel l of automobile, the latter being jacked up abo e the groi that it can driven by the engine withoaf; moving the vehicie itself. A nipple is designed to en E the pump cylinder e one end of a flexible air-pipe 13-, the terminating in the usual nipple for attacment to the air valve casing of mobile tire.

lhe rear end of: the slide is connected by a link 1 to one arm crank lever 15 which is pivotally upon the running board 2 at 16. the handle end 15 of the bell crank is swunr forwardly under the running no"- 2, the I ide i is retracted and the wheel moved out of engagement with the tire .3. When it is desired to move the pump into operative position, the handle 1. is swung III -outwardly and rearwardly until the .hort

arm of the bell crank lever engages a str 3' 17, whereupon the Wheel 10 will be mo into forcible engagement with. the tire i served that the link 14;; and short are the bell crank lever 1-5 are then svning iii" wardly slightly beyond a dead center D031:-

tion, so that the pressure of the wheer upon the tire l serves to lock the pump operative position. With the vehicle e .vrounrl,

A clip 27 is iletechebly applied to of the spokes of the Wheel 1, seicl clip carrying e. spindle 27 which is connected by 9. pi men 28 to the end. of the piston incl 29 of the pump. This pitman is detachable, although. when the parts 941 6 55". somblccl, as indicated above, it will be obvious that the pump will be ectuetecl when the drive Wheel 1 of the vehicle is rotated.

The usual flexible tube 30 is provirlecl for conveying air pressure from the pump to one of: the tires.

having tune descrihec the inveneion,

smell rs Patent is 7 1. A tire pump attachment for eutomol biles, including in combination a slide mounteil upon the running board, e'pump carried by the slide, a Wheel carried by the slicle and operetively connectexl to the pump,

operating lever mounted upon the runboard, a link connection between the ope sting lever and the slide for moving the slide to bring the wheel thereof into engagement with the tire of one of the automobile drive Wheels, and stop means for limiting the movements of the operating lever when the lever and link have been swung slightly beyond. a dead center encl the slide is in operative position.

2. A the pump attachment for automobiles, including in combination a slide mounted on the running board, a pump cerriecl by the slide, a Wheel carried by the slide and operatively connected to the pump, means for moving the slide to bring the Wheel thereof into engagement with the tire of one of the automobile drive Wheels, and a. housing inclosing the slide and formed with s ClOOl constructed to be. automatically opened when the slirle is moved into operative position.

3. A tire bump attachment for automobiles, inclining in combination a. sli le mounted upon the running board, a. pump carried by the slicle e bracket arm prcjectin frsom the slicle, e grooved wheel jour- D nelecl upon the bracket and operetively connected to thepump, e lever operetively connected to the slicle for moving the same to bring the grooved Wheel into engagement with. tire of one of the automobile drive wheels, e casing incloeing the slide one. formed with e hingecl door, a. spring normally holding the hinged door in 2. closed position, encl e roller on the slide for engaging the hinge-cl door to automatically open the same when the slixle is movecl into operative position.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
